Chapter 9 Behaviors 309
In the following image, the Orbit Around (Simulation) behavior is applied to the small blue circle.
The large orange circle is assigned as the object that the circle moves around. The red animation
path represents the motion the small blue circle travels over its duration. The Orbit Around
behavior is the same duration (240 frames) as the large circle to which it is applied.
In the next image, the Orbit Around behavior is trimmed in the Timeline to a shorter duration
(140 frames) than the object to which it is applied. Notice the change in the shape of the
animation path: At frame 140, where the Orbit Around behavior ends, the object (the small blue
circle) stops moving around its target and continues moving o the Canvas. The Orbit Around
behavior—the active force—is no longer present, but the motion of the circle does not stop.
Move behaviors in time
In addition to changing a behavior’s duration, you can also move its position in the Timeline
relative to the object under which it’s nested. This lets you set the frame where that behavior
begins to take eect.
Move a behavior in the Timeline
1 Click anywhere in the middle of a behavior’s bar in the Timeline.
2 Drag the behavior to the left or right to move it to another position in the Timeline.
As you move the bar, a tooltip displays the new In and Out points for the behavior. The tooltip
also displays the delta value, which shows the number of frames you have moved the bar.
Change the oset of Parameter behaviors
Many Parameter behaviors have two additional parameters, Start Oset and End Oset, used to
change the frame where a Parameter behavior’s eect begins and ends.
